148 Airbag system
-The Advanced Airbag System can deploy
in accordance with the .,low risk" option
for 3- and 6-year-old children under the U.S . Federal Standard if a child with elec
trical capacitance greater than the com bined capacitance of a typical one-year
old infant restrained in one of the for
ward facing or rearward-facing child
seats with which your vehicle was certi
fied is on the front passenger seat and
the other conditions for airbag deploy ment are met.
- Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe
cially 12 years and younger, should al
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured.
The front Advanced Airbag System supple
ments the safety belts to provide additional
protection for the driver's and front passeng
er's heads and upper bodies in frontal crashes .
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up
right, wearing your safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to meet the "low risk" re
quirements for 3 and 6 year-old children on
the passenger side and very small adults on the driver side. The low risk deployment crite
ria are intended to help reduce the risk of in
jury through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In addition, the system has been certified to
comply with the "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard
c::> page 170, Child restraints and
Advanced front airbag system.
"Suppression" requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re
strained on the front passenger seat in one
of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com
pliance with the US Safety Standard
i=>page 170,
-When a person is detected on the front pas
senger seat that has an electrical capaci
tance that is more than the total electrical
capacitance of a child that is about 1 year
old restrained in one of the rear-facing or
forward -facing infant restraints (listed in
Federal Motor Vehicle Safety Standard 208
with which the Advanced Airbag System in
your vehicle was certified) , the front airbag
on the passenger side may or may not de
ploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to
tal electrical capacitance on the front passen ger seat that requires the front airbag to be
turned off. If the
PASSENGER AIR BAG OFF
light does not come on, the front airbag on
the passenger side has not been turned off by
the control unit and can deploy if the control unit senses an impact that meets the condi -
tions stored in its memory. ..,_
If the total electrical capacitance registered
on the front passenger seat is more than that
of a typ ica l 1 year-old, but less than the
weight of a small adult, the front airbag on the passenger side may deploy (the
PA SSEN
G ER AIR BA G OFF
light does not come on) .
For example, th e air bag m ay depl oy if :
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld seats listed
¢ page 170),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
I f the front passenger airbag is turned
off, the
PA SSENGER AIR BA G OFF light in the center
of the instrument panel wi ll come on and stay
on.
If the front passenger airbag deploys, the
F ederal Standard requires the a irbag to meet
the " low risk" deployment criteria to help re
d uce the risk of injury through interaction
with the airbag. "Low risk" deployment occurs
in those crashes that take place at lower de
celerations as defined in the electronic control
un it
o page 154 .
Alwa ys rem ember: Even though your vehicle
is equipped with Advanced Airbags, the safest
place for children is properly restrained on the
back seat. Please be sure to read the impor
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS.
A WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- If you are unres trained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of inj ury is much highe r.
- You w ill also receive serio us inju ries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in
flates -even with an Advanced Airbag
¢ page 142 .
Airbag system 149
A WARNING
A child in a rearward-fac ing ch ild seat in
stalled on the front passenger seat will be
seriously inju red and can be killed if the
front airbag inflates -even w ith an Ad
vanced A irbag System .
- Although the Advanced Airbag System in
your veh icle is designed to turn
off the
front airbag when a rearward-facing child res traint has been installe d on the
front passenger seat, nobody can abso
lutely guarantee that dep loyment is im
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild seat
or infant carrier with great force and will
smash the child seat and child against
the backrest, center armrest, door, or roof.
- Always install rearward-facing chi ld re
straints on the rear seat .
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i
ately in sta ll the rear-fa cing child seat in a
rea r seat ing pos ition and have the airbag
system inspected by your Audi dealer.
A WARNING ,-
If, in except iona l circumstances, you must
install a forward-facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never put the forward-facing child re
straint up against or very near the instru ment panel.
- Always move the passenger seat into its rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-fac ing ch ild restra int . Th e •
-
•
-Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
driver seat from the vehicle.
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or put them on the seat. The capacitive
passenger detection mat in the front
passenger seat will not function properly
if it is punctured .
- Never carry things on your lap or carry
objects on the front passenger seat.
Such objects can influence the capaci
tance registered by the capacitive pas senger detection system, so that incor
rect information is provided to the airbag
control unit.
- Never store items under the front pas
senger seat. Parts of the Advanced Air
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper
ly.
- Never place seat covers or replacement
upholstery that have not been specifical
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag
in the seat backrest from deploying prop
erly .
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat , never install any child restraint sys
tem on this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger
seat. The additional layers prevent the
capacitive passenger detection system
from accurately measuring the capaci
tance of the child safety seat and/or the
person on the seat and thus keep the Ad-
Airbag system 151
vanced Airbag System from working
properly .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device or power inverter) on the
front passenger seat if the device is con
nected to the 12-volt socket or the ciga
rette lighter socket. Such devices can in
fluence the capacitance registered by the
capacitive passenger detection system,
so that incorrect information is provided
to the airbag control unit.
- If you must use a child restraint on the
front passenger seat and the child re
straint manufacturer's instructions re
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re
straint is installed on the front passen
ger seat .
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install child restraint in a rear seat
ing position and have the airbag system
inspected by your Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it
immediately.
- If liquid soaks into the front passenger
seat, this can keep the airbag system
from working properly and may, for in stance, deactivate the passenger frontal
airbag. If this happens, the
PASSENGER
AIR BAG OFF
light will come on and stay
on together with the airbag indicator light
rl in the instrument cluster .
- If liquid is pooled on the seat, but has
not soaked in, this may also keep the air
bag system from working properly and
cause the passenger frontal airbag to be
enabled (turned on), even though there is a properly installed child restraint sys
tem on the seat . Wet towels or other wet
things on the seat cushion can have the

same effect . If the front passenger
frontal a irbag is turned on, the
PA SSEN ·
GER AIR BAG OFF
light light will go out.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side a irbags supplement the protect ion of
fered by the front three-point safety be lts
with pretensioners and load limiters and the
ad justab le head restraints to he lp red uce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor
tant information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced Airbag System
and the activation of the safety be lt preten
sioners depend on the dece lerat ion measured
by the crash sensors and registered by the
electronic control un it . The amount of infla
tion of the front airbags can also be adapted
to the front seat position, depend ing on the
d istance between the respective front seat
and the steering wheel or instrument panel as registered by sensors in the seats. Crash se
verity depends on speed and deceleration as
well as the mass and stiffness of the vehicle
or object invo lved in the crash.
On the passenger s ide, regard less of safety
be lt use, the front passenger fro nta l airbag
will be turned off if the electrical capacitance
measured by the capacitive passenger detec
tion system on the front passenger seat is less
than the amount programmed in the electron·
i c control unit . The front passenger frontal air
bag will also be turned off if the capac itance
measured by the system for the front passen
ge r sea t equa ls tha t of an infant of abo ut one
yea r of age in one of the child sea ts tha t was
used to certify the Advanced Airbag System
u nder Federal Motor Vehicle Safety Standard
208 . T he

A WARNING
-To reduce the risk of injury w hen an a irbag
in flates, always wear safety be lts properly.
- If you are unrestra ined, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your risk of injury is much h igher .
- You will a lso receive se rious injuries and
could even be killed if you a re up aga inst

How knee airbags work
Applies to vehicles: with knee airb ags
The risk of injury to the leg area can be re
duced by fully inflated knee airbags.
Fig. 149 Inflated airbags protecting in a frontal coll i
sio n
The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collisions .
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the lower part of the instrument panel and the
driver and the lower part of the instrument panel and the front passenger¢
page 152,
fig. 146.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
All of this takes place in the blink of an eye, so
fast that many people don't even realize that
the airbags have deployed . The airbags also
inflate with a great deal of force and it is im
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim
it the occupant's forward movement and help
to reduce the risk of injury.
Airbag system 161
Important safety instructions on the
knee airbag system
Applies to vehicles: wit h knee airbags
Airbags are only supplemental restraints . Al
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags to provide supplemental protection.
_&. WARNING .. -
An inflating knee airbag can cause serious injury. Wearing safety belts incorrectly and
imprope r seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you a re seated too close
to any of the airbag locations. When ad
justing their seat positions, it is impor
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances:
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru
ment panel.
- at least 4 inches (10 cm) between the
knees and the lower part of the instru
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the seat is improperly positioned and you are
not wearing your safety belt . The risk in
creases even more should the airbag de
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter
fering with the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front
